DETAILED DESCRIPTION

[0017] To make the the technical solutions of the present disclosure more apparent, the following will describe the fastener and the fastener assembly according to the present disclosure with reference to specific embodiments and accompanying drawings.

First Embodiment

[0018] Fig. 1 is a schematic diagram showing a fastener 1 according to a first embodiment of the present disclosure when the fastener is 1 fixed to a first fixing member. Fig. 2 is a diagram showing a perspective view of the fastener 1 shown in Fig. 1. Fig. 3 is a schematic diagram showing configurations of fastening holes 21, 22 and a position limit hole 23 of the first fixing member. As shown in Fig. 1 to Fig. 3, the fastener 1 includes a position limit column 13, an elastic member 14, and at least one fastening hook 11. The elastic member 14 is disposed at a bottom portion of the position limit column 13. The first fixing member includes a fastening hole 21 disposed at a portion corresponding to the fastening hook 11. The first fixing member includes a position limit hole 23 disposed at a portion corresponding to the position limit column 13.

[0019] As an example, the first fixing member may be provided by a bottom panel 2. When the fastening hook 11 is placed in the vicinity of the fastening hole 21, the position limit column 13 is pressed against the bottom panel 2 and the elastic member is in a deformed state. Thus, the elastic member generates an elastic force in a rebound direction. When the fastener 1 moves to a predetermined position, the position limit column 13 falls in to the position limit hole 23 under the elastic force. Thus, the fastener 1 is fixed at a proper position. When the position limit column 13 falls into the position limit hole 23, the fastening hook 11 engages with the fastening hole 21 and the fastener 1 is fixedly connected with the first fixing member 2. As described above, when fixedly connecting the fastener 1 with the first fixing member 2, no screws are used. Thus, the fastener has a simple structure. Further, when replacing the fastener, for example, equipping and dismounting the fastener, an operator does not need any professional tools. Thus, the whole work can be more convenient and efficient, and can reduce manpower cost and time cost.

[0020] In the present embodiment, there are two fastening hooks. One fastening hook 11 is disposed at one end of the fastener 1, and the other fastening hook 12 is disposed at the other end of the fastener 1. Correspondingly, the first fixing member (for example, bottom panel 2) includes two fastening holes. One fastening hole 21 is disposed at a portion of the bottom panel 2 corresponding to the fastening hook 11. The other fastening hole 22 is disposed at a portion of the bottom panel 2 corresponding to the fastening hook 12. In the actual application, the number of the fastening hooks may be greater than two. Multiple fastening hooks may be distributed at different portions of the fastener 1 and the fastening hooks are uniformly distributed for ensuring a uniform force receiving. With this configuration, the fastener 1 can be fixed to the bottom panel 2 more tightly.

[0021] Alternatively, the position limit column 13 may be disposed between the fastening hook 11 and the fastening hook 12. Preferably, the position limit column 13 is disposed at a center portion between fastening hook 11 and the fastening hook 12. The position limit column 13 cooperates with the position limit hole 23 for fixedly connecting a position of the fastener 1. When the position limit column 13 is disposed at a center portion of the two fastening hooks 11 and 12, the fastener 1 receives a force from the position limit column 13 more uniformly for fixedly connecting the fastener 1. Thus, the fastener 1 can be more tightly fixed at a proper position.

[0022] In the present embodiment, the elastic member is provided by an elastic plate 14. One end of the elastic plate 14 is fixed to the fastener 1. On the other end of the elastic plate 14, the position limit column 13 is disposed. Alternatively, a free end of the fastening hook 11 may be disposed in a first direction (that is, mounting direction). The first direction is identical to a moving direction of the fastener 1 when equipping the fastener 1. Thus, the fastening hook 11 can be smoothly engaged with the fastening hole 21, and the fastener can be more tightly fixed to the bottom panel.

[0023] Fig. 4 is a schematic diagram showing the fastener 1 shown in Fig. 1 when the fastener 1 is in an equipped state. Fig. 5 is a diagram showing a perspective view of multiple fasteners and the first fixing member (for example, bottom panel 2) when they are fixed together. As shown in Fig. 4 and Fig. 5, the fastening hook 11 and the fastening hook 12 are respectively positioned in the vicinity of the fastening hole 21 and in the vicinity of the fastening hole 22. At this time, since the position limit column 13 is pressed against the bottom panel 2, the elastic plate 14 is in a deformed state. Thus, the elastic plate 14 generates an elastic force in a rebound direction. When moving the fastener 1 in the first direction (that is, mounting direction) and the position limit column 13 is moved to right above portion of the position limit hole 23, the position of the fastener 1 is referred to as the predetermined position. At this time, the position limit column 13 falls into the position limit hole 23 under the elastic force of the elastic plate 14. Thus, the position of the fastener 1 is fixed. At the same time, the fastening hook 11 is engaged with the fastening hole 21, and the fastening hook 12 is engaged with the fastening hole 22. Thus, the fastener 1 is fixedly connected with the bottom panel 2. Above described mounting of the fastener does not use any professional tools, and does not need screw multiple screws between the bottom panel and the fastener. Thus, the whole mounting work or dismounting work can be more convenient and efficient, and manpower cost and time cost can be reduced. Accordingly, working efficiency can be improved.

[0024] The following will describe a dismounting of the fastener 1. First, the position limit column 13 is departed from the position limit hole 23 using any method. For example, the elastic plate 14 is levered up at an opposite side of the position limit column 13 using finger or other proper tools. Alternatively, the position limit column 13 is pressed at one side using any proper tools so that the position limit column 13 departs from the position limit hole 23. Then, in the second direction (that is, dismounting direction) opposite to the first direction, the fastener 1 is moved. With this moving, the engagement between the fastening hook 11 and the fastening hole 21 is released, and the engagement between the fastening hook 12 and the fastening hole 22 is released. At the end, the fastener 1 can be removed from the bottom panel 2. Above-described dismounting of the fastener does not use any professional tools. Further, no screws need to be removed between the bottom panel and the fastener. Thus, the whole mounting work or dismounting work can be more convenient and efficient, and manpower cost and time cost can be reduced. Accordingly, working efficiency can be improved.

[0025] Preferably, the position limit column 13 and the elastic plate 14 are formed integrally with each other. More preferably, the whole fastener 1 is formed as a single piece. When forming as a single piece, the fastener has a more simple structure, and the mounting and dismounting becomes more convenient and efficient.

[0026] The fastener according to the present embodiment includes the position limit column, the elastic member, and at least one fastening hook. The elastic member is disposed at the bottom portion of the position limit column. The first fixing member includes the fastening hole disposed at the portion corresponding to the fastening hook, and the first fixing member includes the position limit hole disposed at the portion corresponding to the position limit column. When the fastener moves to the predetermined position, the position limit column falls into the position limit hole and the fastening hook engages with the fastening hole. Thus, fastener is fixedly connected with the first fixing member. This kind of fastener has a simple structure and does not need screws for equipment. Thus, equipment and dismounting do not need professional tools, and are convenient and efficient. Thus, this fastener can reduce manpower cost and time cost.

In an actual application, the fastener assembly may be a display apparatus, the first fixing member may be a display monitor main body, and the second fixing member may be an outer cover. Any other apparatuses having the structures disclosed in the present disclosure are included in the scope of the present disclosure.

[0029] Preferably, the fastener 1 includes a lip at a side away from the first fixing member. The lip engages with the protruded portion for fixedly connecting the first fixing member with the second fixing member. As shown in Fig. 6, in the present embodiment, the fastener 1 includes the lip 15 at a side away from the bottom panel 2, and the lip 15 engages with the protruded portion 31 of the lamp cover 3 for fixedly connecting the bottom panel 2 with the lamp cover 3. When equipping, the lamp cover 3 is placed on the bottom panel 2 so that the fastener 1 is displaced from the protruded portion 31. Then, the lamp cover 3 is rotated so that the lip 15 engages with the protruded portion 31 for fixedly connecting the bottom panel 2 with the lamp cover 3.

[0030] In the present embodiment, the number of the fasteners 1 is three, and the number of the protruded portions 31 is three. In an actual application, the number of the fasteners 1 may be three to six, and the number of the protruded portions 31 may be three to six. The number of the fasteners 1 and the number of the protruded portions 31 may also be increased corresponding to actual needs. Preferably, the fastener 1 is formed integrally with the lip 15, and the lamp cover 3 is formed integrally with the protruded portion 31. By forming integrally, the lamp can have a more simple structure and mounting and dismounting becomes convenient and efficient.
